<p data-start="901" data-end="1266">However, understanding how water pressure works is crucial before buying such a product. True pressure washers use motors or pumps to increase water pressure significantly, often reaching thousands of PSI (pounds per square inch). A simple hose attachment like the Qinux Aquoxis cannot create additional pressure&mdash;it can only control the flow and direction of water.

The difference between perceived pressure and real pressure is important here. Narrowing the water stream can make it feel stronger, but it doesn&rsquo;t have the same cleaning power as a machine-built pressure washer.
